5.2.1 Easy set-up
• When the unit is supplied with operating voltage for the first time, the probe
length, the medium to be detected and the type of probe used must be entered�
Then the unit is ready for operation (→ 10.2)�
• If necessary, parameters for the output signals and optimisation of the
monitoring functions can be set (→ 10.3 to → 10.5)�
• All settings can also be carried out before installation of the unit�
• Reset to the factory settings is possible�
• Electronic lock can be set to prevent unintentional operations�
5.2.2 Display functions

5.2.3 Switching functions
The unit signals via 4 switching outputs OUT1���OUT4 that a set limit level has
been reached or that the level is below the limit value� For each output the
following switching functions can be selected:
• Hysteresis function / normally open (fig� 5-3): [OUx] = [Hno]�
• Hysteresis function / normally closed (fig� 5�3): [OUx] = [Hnc]�
First the set point (SPx) is set, then the reset point (rPx) with the requested
difference�
• Window function / normally open (fig� 5-4): [OUx] = [Fno]�
• Window function / normally closed (fig� 5-4): [OUx] = [Fnc]�
The width of the window can be set by means of the difference between
FHx and FLx� FHx = upper value, FLx = lower value�
